This may a bit early and maybe pre-mature.
Now that the Power8 PCI slots are again "hot swappable" (Power 5 was, Power 6 and Power7 not).
Current Power7 is configured with 2 loops, (4 5913) each 5913 pair is split in one of two 5877, in case of drawer and/or loop failure.
If I were to upgrade to a Power8, at some point, I theoretically could eliminate my two 5877, put all 11 slots in Power8 CEC.
Not only would this eliminate all expansion drawers, but also both GX++ loops.
Hardware maintenance would also be reduced.
One negative would be that I'd be maxed, no room for expansion, currently I have 9 empty slots.
Any other negatives or thoughts from the group.
